I have a question about YM3110. It has been sitting a few months. It runs, but it won稚 idle. Anyone have any ideas?

Whitetail, have you ran any injector cleaner thru it??
Usually what happens is the fuel get "gummy" & slows down the movement of the control rack to the point the governor cant do its job.
& the same goes w/ the engine oil.. The "top side" is lubed by fuel & the "bottom side" by engine oil..
I did 1 last month that the oil was so burnt/overheated, it stuck the rack & wouldn't idle.. had very hard start & very slow acceleration..
Any of these sound familiar??

No, I haven't tried that. As far as the oil, it is new oil, oil filter, fuel filter. But it could probably use the injectors flushed. What injector cleaner do you recommend?

Schaffer makes the BEST..
everybody uses Power service because its everywhere..
Lucas makes a good one too. I've personally seen Lucas do amazing things.. wouldna believed it, if I hadn't seen it.
